Shenzhen Airlines plans to introduce widebody aircraft to its fleet by 2015.
The carrier is looking to add between three and five of these aircraft to its fleet, says its vice-president Wang Jie on the sidelines of a ceremony to mark the airline's Star Alliance membership.
Wang declined to say which aircraft type the carrier is looking at, or what routes they will possibly serve.
An airline source, however, says the carrier is likely to look at Airbus A330 and Boeing 787 aircraft. It could launch services to Australia using these jets, adds the official.
Next year, Shenzhen Airlines could also launch some international services to Southeast Asian countries such as Thailand, says Wang.
He adds that the carrier also expects to work more closely with fellow Star Alliance members such as Singapore Airlines, All Nippon Airways and Asiana Airlines.
Flightglobal Pro shows that Shenzhen Airlines operates 119 narrowbodies. These are used mostly on domestic routes. The airline plans to grow its fleet to 170 aircraft by 2015.
